Encyclopedia

Ecosystem is a community made up of living organisms and nonliving components such as air, water, and mineral soil. Ecosystems can be studied in two different ways. They can be thought of as interdependent collections of plants and animals, or as structured systems and communities governed by general rules. The living (biotic) and non-living (abiotic) components interact through nutrient cycles and energy flows. Ecosystems include interactions among organisms, and between organisms and their environment. Ecosystems can be of any size but each ecosystem has a specific, limited space. — Wikipedia

Types of Environmental Ecosystems (Amy Harris, Sciencing)

Biome is a community of plants and animals that have common characteristics for the environment they exist in. They can be found over a range of continents. Biomes are distinct biological communities that have formed in response to a shared physical climate. “Biome” is a broader term than “habitat”; any biome can comprise a variety of habitats.

A ‘biota’ is the total collection of organisms of a geographic region or a time period, from local geographic scales and instantaneous temporal scales all the way up to whole-planet and whole-timescale spatiotemporal scales. The biotas of the Earth make up the biosphere. — Wikipedia

Science

Ecology is the branch of biology which studies the interactions among organisms and their environment. Objects of study include interactions of organisms with each other and with abiotic components of their environment. Topics of interest include the biodiversity, distribution, biomass, and populations of organisms, as well as cooperation and competition within and between species. Ecosystems are dynamically interacting systems of organisms, the communities they make up, and the non-living components of their environment. Ecosystem processes, such as primary production, pedogenesis, nutrient cycling, and niche construction, regulate the flux of energy and matter through an environment. These processes are sustained by organisms with specific life history traits. — Wikipedia

  • Natural ecosystems protect against climate change
    on December 10, 2019 at 4:17 pm

    The identification of natural carbon sinks and understanding how they work is critical if humans are to mitigate global climate change. Tropical coastal wetlands are considered important but, so far, there is little data to show the benefits. This study showed that mangrove ecosystems need to be conserved and restored as part of the battle against rising carbon levels in the atmosphere.

    on December 10, 2019 at 4:17 pm

    A new study has shown that using a drone to film hippos in Africa is an effective, affordable tool for conservationists to monitor the threatened species' population from a safe distance, particularly in remote and aquatic areas.

  • Megadroughts fueled Peruvian cloud forest activity
    on December 9, 2019 at 6:19 pm

    New research has found that strong and long-lasting droughts parched the usually moist Peruvian cloud forests, spurring farmers to colonize new cropland. Findings also included evidence that recovery from some climate change-related damage is possible.

  • Some forests crucial for climate change...
    on December 9, 2019 at 6:19 pm

    Researchers have identified forests in the western United States that should be preserved for their potential to mitigate climate change through carbon sequestration, as well as to enhance biodiversity.

    on December 5, 2019 at 7:51 pm

    Recycling biotechnology byproducts can enhance soil health while reducing carbon emissions and maintaining crop yields.

    on December 11, 2019 at 7:00 pm

    Botanists from Trinity College Dublin have discovered that "penny-pinching" evergreen species such as Christmas favourites, holly and ivy, are more climate-ready in the face of warming temperatures than deciduous "big-spending" water consumers like birch and oak. As such, they are more likely to prosper in the near future—with this pattern set to be felt more strongly in cooler climates, such as Ireland's.

    on December 10, 2019 at 2:50 pm

    The health and wellbeing of humans is underpinned by the natural world. Living nature in the form of ecosystems and biodiversity is the world's life support system. It is crucial, but under threat.

    A study by Oregon State University researchers has identified forests in the western United States that should be preserved for their potential to mitigate climate change through carbon sequestration, as well as to enhance biodiversity.

    on December 9, 2019 at 5:01 pm

    Scientists from around the world have assessed the planet's 78 mountain glacier-based water systems. For the first time, they ranked them in order of their importance to adjacent lowland communities while assessing their vulnerability to future environmental and socioeconomic changes. These systems, known as mountain water towers, store and transport water via glaciers, snow packs, lakes and streams, thereby supplying invaluable water resources to 1.9 billion people globally—roughly a […]

  • The Arctic atmosphere: A gathering place for dust?
    on December 9, 2019 at 4:50 pm

    The atmosphere of the central Arctic is polluted with fine dust from Siberia and North America. This was the result of a preliminary evaluation of the first lidar measurements carried out by the Leibniz Institute for Tropospheric Research (TROPOS) during the one-year MOSAiC expedition on board the RV Polarstern. For the first time, a multi-wavelength lidar was used during polar night in the central Arctic, which can measure dust particles at altitudes of up to 14 kilometres with laser pulses […]
